Retardation accuracy vs wavelength (nm)
Achromatic Quartz-MgF₂ Wave Plates operate over a broad wavelength range, compared to zero-order quartz wave plates: 400-700nm, 650-1100nm, 1100-1700nm.
- Material: Birefringent crystals
- Assembly: air spaced or optically cemented
- Achromatism:
± 3% @ 400 – 700 nm
± 2% other wavelengths
- Field: 5°
- Wavefront deformation: λ/10
- Thickness: around 1mm
Fast and slow axis are perpendicular to the section.
- Antireflection coating: R average ≤ 0.35%
